PRINTING-PRESS GAGE.

Specification of Letters Patent.

Patented Feb. 1, 1.921.

Application filed January 26, 1920. Serial No. 354,316.

To all whom it may concern:

Be it known that I. NATHANIEL D. PON- NAY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Printing-Press Gages, of which the following is a specification.

This invention relates to printing appa- Fatus and more particularly to paper gages attachable to the platens of printing presses, and has for its object to provide a paper gage which can be applied with facility to the platen and that can be independently adjust ed at the requisite angle as may be required to conform to the alinement of the form on the press bed, and'further has for its object to provide a device that is simple, substantial, practicable and inexpensive and consists of the construction embodiments of which are illustrated in the accompanying drawings and described and claimed herein.

Figure 1 is a perspective of a platen with the improved gages applied.

Fig. 2 is a perspective of a platen showing the draw sheet slitted to receive the gages.

Fig. 3 is a perspective showing a set of gages of modified construction.

Y sheet.

The invention consists essentially of a bottom member or plate 2 made of suitable material, preferably metal, rather thin in proportion to its length and width and having its front transverse edge beveled at 3 and its rear edge beveled 1134 upwardly and rearwardly to facilitate the attachment of the gage to the usual draw sheet S, shown. in Figs. 1, 2 and 8 as applied to the platen P and secured by the usual foldable clips C.

The bottom member 2 is provided with a fixed central upwardly extending stud 5 of suitable proportions having a reduced neck or annular groove 6 above which the stud is threaded as atl'? to receive the clamping nut 8. This nut is designed to pressa suitable clamp block or cap 10, Fig. 9, downwardly soas to bite upon and engage the insorted portion of the draw sheet S when the bottom plate or member 2 has been mounted upon the draw sheet, as clearly shown in Figs. 1 and 8. The draw sheet is perforated -at suitable locations by pairs of parallel slits 11 spaced apart sufficiently to permit the introduction of the gage bottom plate 2 'so that it will be overlapped by the edges of I the sheet S parallel to the opposite sides of the slits, the body of the plate 2 overlying the central free portion 12 of the strip or The cap block 10 is substantially plane in its uppersurface and its lower face is longitudinally channeled as at 13 forming a series of parallel body portions 14, the front ends of which form downwardly extending supporting parts 15 to rest upon the adjacent upper face of the bottom 2, and the block 10 is riveted or otherwise attached to the plate 2 as by rivets 16 passing through apertures 17 in the cap and plate members.

That portion of the cap block to the rear ofv the supporting parts 15 provides a resilient tongue or plate that overlies the central portion of the base plate and which resilient tongue is pressed downwardly when nut 8 is rotated so that it moves downward upon stud 5.

The rear ends of the body portions 14 are shown as toothed at 18 to coiiperate with the toothed portion 19 on the upper face of the plate 2, So that when the cap 10 has been applied, as above described, with the threaded part 7 of the stud 5 extending upwardly through an aperture provided for its recaption in the cap 10; then after the plate 2 has been inserted beneath the draw sheet S and pressed rearwardly sothat a portion of the sheet passes between the relatively spaced teeth l8and 19, then when the clamp nut 8 is turned down on the screw 7, the resilient rear portion of the plate 10 is flexed downwardly the inserted portion of the draw sheet is firmly clamped between said teeth and thus the gage is held firmly in position. llt will be seen that this permits the relative angular adjustment of the gage upon the sheet S as may be desired to conform with alinement of the type form mounted in the press.

To facilitate the guiding of the sheet or blank B to be printed into position and adjustment upon the several gages that may have been mounted on the draw sheet S .each of the gages is provided with a forwardly extending and removable finger 25 of suitable contour, the finger being in the form of a hair-pin and its spaced ends insertible into the channels 13 in the lower face of the cap 10, the inner surfaces of the arms of the fingers 25 passing into the grooved portion 6 (if the stud 5 and being clamped securely thereon when the clamp nut 8 is advanced on the screw 7.

Preferably, the guide finger 25 is bowed outwardly and upwardly, as plainly shown in Fig. 8, so thatthe edge of the paper will pass freely between the outer end of the finger and the adjacent surface of the draw sheet which overlaps the inserted end of the bottom 2 of the gage.

There is shown in Fig. 12 a slightly modified form of bowed finger in which case the outermost end of the finger is deflected upwardly as at 25' to permit the ready insertion of the edge of the paper, and then somewhat to the rear of the end 25 of the finger is bowed upwardly as at 25 this forming a spring structure normally pressing the finger end 25' downwardly on to the draw sheet S to facilitate in holding the paper snugly down on the platen.

A simple and preferred embodiment of the invention is illustrated in Figs. 14 to 19 inclusive wherein the gage isshown as made up of one integral piece of sheet mate rial of suitable length and width, the sheet forming a bottom 30 of suitable dimensions at one end of which the metal is doubled upon itself as at 31 and thence is provided with an upwardly extending shoulder 32 forming the stop surface, as seen in Fig. 19, for the inserted sheet B to be printed upon. The sheet is continued rearwardly from the shoulder 32 in-a plane substantially parallel to the bottom plate or portion 30 and forms the top 33 extending rearwardly to a suitable distance and provided with a downwardly turned lip 34 beneath which the draw sheet S is inserted, as in Fig. 19, to overlap the adjacent portion of the base 30.

Intermediately the length of the top 33 between the shoulder 32 and the lip 34 there extends upwardly a screw 35 suitably secured on the upper surface of the bottom 30 so as to project through an aperture 36 pro vided therefor in the top 33, this screw being designed to receive a clamp nut 37 which when turned down presses upon the yielding leaf 33 so as to cause the lip 34 to bind upon and hold the inserted portion of the draw sheet S.

The guide finger 25 is designed to be clamped beneath the clamp nut 37 in the same manner as described relative to the form shown in Fig. 8, but in modified form the top or yielding leaf 33 is formed with depressed portions as grooves 38 extending parallel and into which the arms of the finger 25 can be inserted so as to be engaged by the lower face of the clamp nut 37.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

In a printing press gage, a base plate, a stud seated in and projecting upwardly therefrom, a top plate rigidly fixed at one end of said base plate to one side of said stud, which top plate is perforated to receive the stud, a nut seated on the threaded upper end of the stud, the under side of the top plate being slotted to receive the legs of a paper guiding finger, and parts of the top surface of the base plate and adjacent parts of the under surface of the top plate being corrugated in order to firmly clamp an interposed sheet.
